– Something that could affect users’ decisions on FS

• Sufficient Appropriate Evidence

– Sufficient = enough, and depends on risk, judgment, quality ofevidence collected

the misstatements found during the audit.• Record ALL misstatements found (unless trivial)

• Ask mgmnt to correct them, or explain why not• For misstatements they will not correct:

– Get Mgmnt Rep to confirm they are not correcting them

purely due to immateriality


38/76

39/76

ISA 500 – Audit Evidence

• Sufficient Appropriate Evidence:• Sufficient = quantity, depends on risk, quality of

evidence

•

Appropriate = Relevant and Reliable – Relevant = to an assertion

– Reliable = 3rd Party, auditor-obtained, original documents are

better than client-provided and oral


40/76

ISA 500 – Audit Evidence

• Types of audit test:

–Analytical Procedures• Comparing current year with last year, Industry etc.

–Enquiry and Confirmation• Ask questions and get written replies

–Inspection (of documents, of assets)

– Recalc U lation


41/76

ISA 501 – Evidence (Specific Items)

43/76

ISA 510 – New audit clients, Opening

Balances

• Known as “Initial audits”• Audited by another firm last year, or;

• Company never audited before

•

Issues• If Op Bals wrong, likely to affect current year?

• If Comparatives wrong … see ISA 710

• Work• Agree Op Bals to last year’s FS

• Get working papers from the other firm

• If last year’s audit report modified, may affect this year


44/76

ISA 520 – Analytical Procedures

• Used at:• PLANNING (ISA 315 covers this)

• As a SUBSTANTIVE test (part of AEIOU)

• At COMPLETION phase

• Method• Compare auditor EXPECTATION with DRAFT FS

• If expectation uses predicted relationships, and is close todraft figure, may be enough evidence in itself

• Use prior year, Industry, budgets, ratios etc.

• Completion Stage• To take account of figures (and expectations) changing

during audit


45/76

ISA 530 - Sampling

• Aim = REPRESENTATIVE sample• Sample has same characteristics as population

• Then can EXTRAPOLATE results from sample to

population overall• Use statistical sampling (RANDOM + probability theory)


46/76

ISA 530 - Sampling

• Lots of terms to know:• SAMPLING UNIT – item being tested (e.g. an invoice)

• STRATIFICATION – break population into sub-

populations (e.g. by value, or by age)• SAMPLING RISK – risk sample is not representative

• NON-SAMPLING RISK – risk audit staff mess up test

• ANOMALY – error that is clearly a one-off (rare!!)

• TOLERABLE MISSTATEMENT – maximum erroracceptable in a sample (based on Perf Materiality)


47/76

ISA 530 - Sampling

• SAMPLE SELECTION METHODS• Random (best method)

• Value-Weighted (random, where sampling unit is each

individual $)• Block (not good – simple, as it picks a “block” of

transactions or balances, unlikely to be representative)

• Haphazard (audit staff manual attempt to be random,

hard to avoid bias though)


48/76

ISA 540 – Audit of Estimates

• Estimates include:• Uncertain future events

• Valuation of items (e.g. assets)

• If estimate does not turn into actual, this doesNOT mean the estimate was bad at that time!

• Issues – How management measures them – The models used (if relevant)

– Expert used / Assumptions used / level of uncertainty


49/76

ISA 540 – Audit of Estimates

• Audit work on estimates• Prior year v actual (to assess their methods)

• Post y/e latest events

•Assess mgmnt’s estimation methods

• Auditor expectation v the estimate

• Assumptions used by mgmnt – realistic?

• Get a Written Rep confirming best estimate

• Audit the expert (if one used)! (ISA 620)


50/76

ISA 550 – Related Parties

• Audit team should discuss related parties at

planning, as part of fraud assessment

• Enquiry of management as to whether all RP

told to audit team, and all RPT disclosed in FS

• Compare to p/y FS list of RPT disclosed

• Assess company controls to highlight RPT

• Read AGM and Board Meeting Minutes for

discussion of RPT


51/76

ISA 550 – Related Parties

• Clues it is a RPT:

– No obvious business logic to transaction

– Strange price or payment terms

– Non-commercial basis (i.e. not arm’s length)

• If discover RPT yourself (client did not tell

you), inform Audit Committee

• Increase scepticism when dealing with RPT


52/76

ISA 560 – Subsequent Events

• The audit of IAS 10 matters (EARP / PBSE)• PBSE are events between y/e and date FS signed

• Give evidence of company’s position at y/e, then

ADJUSTING• Do not give such evidence, then NON-ADJUSTING

• If non-adjusting, could be so significant to need

DISCLOSURE


53/76

SSA 560 – Subsequent Events

• The problem is this – sometimes the event

that happens BEFORE FS are signed is not

discovered until AFTER FS are signed.

• But if the event was before FS were signed, it

is an IAS 10 EARP and may be adjustable, or

disclosable.


54/76


• Auditor audits as normal (active duty) up to

date audit report is signed (after FS signed).

• After that date, duty becomes “passive”.

• If a EARP is DISCOVERED after FS and Audit Report

signed (but event OCCURRED before FS signed), assess

if it is:

– Adjustable

– Non-adjustable, but disclosable

• Ask Board if they plan to correct the FS (they should do)


55/76


• If directors change the FS: – Check the correction done properly

– Check they changed nothing else!

– The IAS 10 applicable date has now moved forward to the

later date the new revised FS are signed – so audit the gap

– Sign new audit report, with Emphasis of Matter to explain that

the FS were revised, and the initial audit report can be ignored

• If directors refuse to change FS: – Get legal advice

– Speak at AGM

– Consider resignation


56/76

ISA 570 – Going Concern

• Auditor must:• Assess if Going Concern basis of preparation is correct

• Assess any disclosures of GC threats

• FRS 1• FS normally prepared under GC assumption

• This means company expected to continue for > 1 year

• If not, use alternative basis of preparation

• Disclose any significant GC threats in a FS Note


57/76


• Indicators of GC problems• Net liabilities

• Loans need to be repaid soon (or other big outflows)

•Suppliers denying credit

• Loss of key staff / products / markets

• Legal claims / regulatory investigations

• New competitors

• Losses / poor cash position

• Ratio analysis looks bad


58/76


• Audit Work• Review forecasts (and whether assumptions realistic)

• Mgmnt Accounts since y/e for latest results

•Loan agreements

• Board Minutes

• Get a Written Representation

• Recent orders received

• Correspondence with bank

• Availability of cash / assets to sell (or use for secured

loan)


59/76


• If not a GC, but they used GC basis of prep:• Adverse Opinion

• If a GC, but there are threats not disclosed:• “Except for” qualified opinion, or Adverse, depending

on the nature of the missing disclosure

• If a GC, with threats, which ARE disclosed in

FS:• Unmodified opinion, plus Emphasis of Matter

paragraph


60/76

ISA 580 – Written Representations

– All contingent liabilities disclosed

– That any uncorrected misstatements are immaterial

62/76

ISA 600 – Audit of Group FS

• Group auditor fully responsible for opinion• If other firm audited a sub (component auditor),

cannot mention this fact in audit report

• Must understand all subs in the group

• For material subs in group:• If not the auditor, must discuss audit with the sub’s

auditors (the component auditor)

•

Must review audit work of this component auditor• Consider materiality both at Group level, and

for each Sub


63/76

ISA 600 – Audit of Groups

• Bear in mind errors at subs could add up to a

material error at Group level

• Ensure all audit teams in group audit are

aware of fraud issues, and Related Parties

• Ensure Group Auditor’s audit methods in use

by all auditors of all subs• May have to tell component auditors to do additional

work, to comply with group audit methods


64/76

• Is their audit work subject to external monitoring

•

Which audit standards do they follow – In other words, can you rely on the quality of their

work?

66/76

ISA 610 – Using work of Internal Audit

• If client has Internal Audit, its work may be

relied upon by External Audit• External auditor retains responsibility in full for audit

opinion• Only rely if IA work relevant, properly planned and

documented etc.

• Assess IA

–

Independent? – Competent / qualified staff?

– Work done with due professional care

ISA 610 – Using the work of Internal


67/76

ISA 610 – Using the work of Internal

Audit

• Other considerations:• Communicate with IA to help assess risk of material

misstatement in FS at planning

•

For judgment areas of FS, and high risk areas, do notrely much on IA work, EA should do it themselves

• Do not use IA to help with 3rd Party confirmations

• Communicate plans to rely on IA to TCWG (ISA 260)

•

Where relying on IA work, reperform some first toensure it is reliable


68/76

ISA 620 – Reliance on Experts

• Auditor may use an expert to help audit

• If hire OWN expert, not client’s, easier to:

• Get independence

• Control their work
